Its one of the hardest job in the service. Its a very selective process to get into the field and once you are in, you must pass very stressful profiecenies, shotting skills, being able to handle all type of weahter conditions for long hours and days ata time, before you can take what is known as the 'KIll shot'. Their motto is one shot one kill. You also learn from the start when they issue you your snipper rifle. "There are many rifles like this, but this one is mine" You will live with it all the time you are in Snipper School. You will learn how to clean it in the dark, fix jams in the dark. its easy to do it in the sunlight, but you will also need to do it in the black of night.
